I test using CExtGridCellScientific in ProfUIs controls sample application. When I enter the value 1e-14 to the cell with scientific cell type for the first time, the text is shown 1.00e-14 as I expected. But if I tried to edit the cell with the value 1.00e-14 in it, when the control in the cell change to edit box, the value is set to zero. I don’t want the value to be changed. What should I do?
